The Brazilian has no doubts over the Portuguese’s potency, but also feels his own side have enough quality to have their say in the Champions League this term

Paris Saint-Germain defender Thiago Silva knows his side must work hard to try and contain Cristiano Ronaldo when they face Real Madrid on Wednesday.

Les Parisiens entertain the joint-Group A leaders at Parc de Princes hoping to extend their perfect start in the Champions League, although Silva is aware of the threat Real pose

The Brazilian centre-back specificially singled out Madrid’s all-time leading goalscorer Ronaldo, and says the outcome of the match depends on how effective their efforts to keep the Portuguese quiet are.

“It’s difficult to mark Ronaldo,” he told reporters. “I think he has a lot of qualities. He has all the abilities a striker can possesses.

“He’s very good with the head, the right foot, the left foot. His strike his the same whatever the feet. We need to be focused in order to mark that guy.

“We’ll try to work this afternoon in order to find the best way to mark Cristiano, which is not an easy task.”

French champions PSG are eager to taste continental glory this season after winning three consecutive Ligue 1 titles.

And Silva believes the squad have the necessary quality now, following the acquisition of ex-Madrid and Manchester United midfielder Angel Di Maria in the summer.

“I think we can do it. This year we are better than the previous one in my opinion. I think we play much better,” Silva continued.

“We are playing at a higher level when we get the ball. We started the season well compared to the last one. That’s very important for the confidence of the players to start that way.

“Di Maria was a great asset for the club and it helped well. He’s scoring goal. He also marks the wingers. I think we are stronger now. When we have the ball control we are always a threat. The issue is when we do not have it. That’s something we try to work on.

“We are speaking with the coach and between us in order to find the best solution. With the time, we’ll do better.”
